Vietnam U17 and the Three Stages Toward the 2026 World Cup: Reading Tactics From a 29-Name Squad List

That evening I reopened Vietnam U17's squad list exactly three times — an old habit, checking before believing. The first time I read the names. The second time I counted. The third time I noticed what was not in the list: a tactical formation. Nothing. Not a single line about how the team would play, who would partner whom, how deep the defensive block would sit, or which line would press.

That was when I understood I was reading a report about a preparation cycle, not a tactical analysis. And for a U17 team that had just secured a World Cup berth, the gap between those two genres of writing is precisely what deserves attention. Every formation is a lie — until the ball rolls. But this time, no one has even begun to lie yet.

I watched it three times. The third time, I saw what VAR never catches: a team in a screening phase, not a shaping phase.

Context: The team is no longer playing qualifiers — it is preparing for a tournament

Everything needs to be placed in its proper frame. Vietnam U17 has already achieved the biggest objective of a cycle: a berth at the FIFA U17 World Cup. The basis for their presence there is their run at the AFC U17 Asian Cup — a tournament that, under AFC rules, forms part of the pathway to the World Cup. From here, the competitive dynamic changes entirely. No more points to accumulate in qualifying, no more fear of early continental elimination in the existential sense. Instead, a new state: the milestone has been reached, and now expectations must be managed.

At the finals, Vietnam U17 sits in Group G alongside Mali, Belgium and New Zealand. Any analyst who glances at this group raises an eyebrow. Mali is one of football's strongest youth exporters in Africa — a nation that produces endless names quickly absorbed by European academies. Belgium represents the methodical development model of UEFA, where positional structure and tactical discipline are taught very early. New Zealand brings a different school — athleticism, speed and direct, OFC-style football.

The institutionally notable point is that the finals format keeps expanding. From the traditional U17 number, the tournament has grown to 48 teams, opening more doors for Asian and Southeast Asian nations. This is a structural signal, not mere luck. A wider door means more slots, meaning the distance between a "mid-tier Asian team" and a "World Cup ticket" has shortened. But a wider entrance does not make the arena inside any easier.

On the coaching side, head coach Cristiano Roland has been confirmed to continue. This seems a small fact, but it carries large tactical weight. In youth football, retaining a coach across a preparation cycle usually comes with stability of philosophy and selection. A coach sacked mid-cycle drags along a wave of disruption: the playing style changes, roles change, and faces once trusted can be pushed to the margins. Roland staying means the technical rail is preserved.

Core: Twenty-nine names, one training ground, and a three-stage route

This is where I want to linger longest, because it is the only place in the whole story with a genuine tactical signal.

Calling up 29 players is not an administrative detail. A starting squad at a finals typically needs only about 20 to 23. The number 29 goes far beyond that. In the language of preparation, this signals a screening phase: the coaching staff has not yet settled on a frame, and they want to create genuine internal competition before cutting players. In other words, the 29-man list is a statement that no one is guaranteed a place. It turns every training session into an examination, and every player into a candidate defending his position.

Tactics do not live on the whiteboard. They live in the space between two players. And when you have 29 men competing for roughly 11 positions, that space becomes more crowded than ever — deliberately so.

Alongside the number 29 is another signal: the team has retained the spine from the AFC U17 Asian Cup. Names mentioned such as Van Duong and Chu Ngoc Nguyen Luc in the advanced lines, and most likely goalkeeper Ly Xuan Hoa as the number one, point to a clear philosophy: continuity over rebuild. In a short tournament, cohesion and established connections are worth more than a personnel revolution. Players understand each other, understand each other's movement, and do not need time to reacquaint. It is a reasoned choice, though it carries its own risk.

The preparation route is split into three stages. The first phase takes place at the Vietnam Youth Football Training Centre until around October. Then a training camp in West Asia. Finally, relocation to Qatar, the host of the finals.

This arrangement shows the focus is not purely tactical, but adaptive. Moving from Vietnam's climate to West Asia and then to Qatar is a problem of temperature, humidity, time zones and the daily rhythm of players barely beyond childhood. For U17 players, whose bodies are still developing, heat adaptation and post-exertion recovery differ entirely from their seniors in the national team. These camps are not only for friendly matches, but to acclimatise the body before the tournament begins. A team arriving late, unaccustomed to the climate, can pay the price in the very first match.

From an operational standpoint, organising a camp in West Asia and then Qatar for a U17 team is no small investment. Travel, accommodation, training pitches, foreign friendly opponents — all costly. Without specific figures from the federation, it is very hard to assess the financial sustainability of this programme. But the very existence of a three-stage route is a signal: this youth team is being prioritised at a high level of resourcing by Southeast Asian standards. This is a fact more worth noting than any commentary about a "relaxed training atmosphere" or "effort in every play".

On personnel screening, retaining the Asian Cup spine creates a two-tier model: a core group already validated at continental level, and a competing group around them. The core has the advantage of international match experience, but also faces higher expectation pressure. Newcomers have the advantage of hunger, but lack experience. Who wins a starting place will depend on whether training form converts into the coaching staff's trust.

Contrarian: Three blind spots that optimism is covering

The original report, when I read it, had fairly thin factual density. Many facts carried no specific sourcing, and the commentary was attributed to "the article's author" rather than to any official or coaching staff member. That style of reporting is highly optimism-oriented, and it pushed me toward three blind spots that, in my experience following matches, are always the ones people skip.

The first blind spot is physicality. For years, the structural weakness of Vietnamese youth teams against African and European opposition has lain in one-on-one duels, physical strength in extended phases, and the ability to withstand aerial situations. Against a team like Mali, players often have superior size and speed. Against Belgium, you meet a collective organised to a frustrating degree. In both cases, physicality stops being a secondary factor — it is the foundation on which everything else operates. The fact that the preparation report never mentions this dimension is a notable gap.

The second blind spot is the trap called the "golden generation". Reporting that leans toward serious preparation, with imagery of a team "highly focused" for a world-class tournament, easily leads to expectations beyond short-term reality. When fans are told the team is preparing meticulously for the World Cup, they will automatically expect the team to achieve something great at the World Cup. But a group containing Mali, Belgium and New Zealand is a very hard group for a Southeast Asian side. The most realistic competitive target, in my view, is to play on equal terms and aim for points against New Zealand. If public expectation is pushed too high, even a not-bad result can be read as failure — and that is when the optimistic cycle turns into a critical one.

Morocco does not build a wall. They build a maze. I wrote that when analysing the senior Morocco defensive wall in Qatar two years ago. With Vietnam U17, the problem is even harder, because the opponents are physically stronger and you do not have much time to build such a complex defensive block at this age group.

The third blind spot, and the least discussed, is the risk of player poaching after the tournament. This is the downside of owning a global platform. The U17 World Cup is a giant shop window. Any player who impresses immediately enters the sights of foreign academies and clubs. For names already positioned as mainstays such as Van Duong, Chu Ngoc Nguyen Luc or Ly Xuan Hoa, a successful tournament could significantly accelerate their route abroad. That is good for the individual and for Vietnamese football's reputation. But it also means that spine could be hollowed out before it ripens for the U19, U23 and senior levels. A cycle built with care can dissolve faster than people think, without a sensible retention and development mechanism.

What is truly worth tracking in the coming months

From here, I want to offer a verifiable way of reading. There are signals I will track, and they tell me more than any statement about "determination".

The first is the timing of the official squad cut. When 29 reduces to around 20 to 23, we will clearly see the coaching staff's true selection priorities: do they choose stability or the element of surprise. The final list is a disguised tactical document. It tells us how the team will play, even if no one explains it in words.

The second is the results of training matches during the West Asia and Qatar camps. This is the best proxy for readiness we can access, because tracking data at U17 level is rarely published. No xG, no PPDA, no formation-distance data. Without training matches to substitute, every assessment is guesswork. For a data sceptic like me, having to evaluate a team only by eye and through training observations is a major handicap — but it also reminds me that sometimes data does not exist, and then one must be honest about one's limits.

The third is the result of the first group match. The game against New Zealand, by its placement, may be the most decisive in psychological terms. A good start against New Zealand opens the possibility of competing, and shapes the entire media narrative that follows.

The fourth, and perhaps most important long-term, is the academy transfer story after the tournament. This is where I will apply my exact filter. During a transfer window, noise always drowns out signal. Rumours fly everywhere, but what truly decides lies in contract structure, in the player's age, and in FIFA Regulation Article 19 — the rule governing the international transfer of minors. Any move involving a player under 18 must pass through this strict legal framework. When tracking rumours around Vietnam's young players, I will ask: what is the actual contract clause, and what is merely an agent's wish. That is the only way to know what is really happening.

Takeaway: A question still without an answer

A 29-man list, a retained head coach, a three-stage route and a group featuring Mali and Belgium. That is the entire tactical signal we have.

What I wonder, and what the coming months will perhaps answer: will the coaching staff turn the internal competition among 29 names into a genuine tactical advantage, or merely into pressure on still-too-young legs? Because a team accustomed to proving itself in every training session can either play freely, or play as if being strangled. The result in Qatar will tell us which case they belong to.
